First, the museum is free after 3pm on Sundays, but what they don't tell you is that you can't get the audio guide even if you want to pay for it. Had I known that, i would have gone on a different day. Another reviewer brought up the issue of not all displays have explanations in English. They also show a video in a separate room, but that was also only in Spanish/Catalan. Having said all that, yes it was fascinating for a while, but I was glad to see the exit sign coming up. I also agree with another reviewer who said it lacked humanity. Im glad i saw it, but think I would have had a different experience with the audio guide and all the displays and video in English.
